Definitions

  • the invention relates to a plate mold for producing strands of steel.
  • DE 24 15 224 C3 discloses a plate mold for slabs, the mold walls of which Have cooling chambers that include certain cooling areas.
  • Have cooling chambers that include certain cooling areas.
  • To the water supply and - Drain lines of the broad sides are measuring elements for determining the discharged Heat quantity or the cooling capacities connected. Furthermore, in the measuring elements at the same time an average value of the cooling capacity of the cooling chambers is formed, which is fed to an average former with which the conicity of the narrow sides is controlled can be.
  • the invention has therefore set itself the goal of a generic plate mold for Casting speed between 1.5 and 8 m / min to create an easy and safe Temperature control including the middle of the broadside in the area of the immersion spout enables.
  • a plate mold with water-cooled Narrow side walls that can be clamped between broad side walls, the Broad side walls at least three side by side and independent of each other Have cooling segments, are divided symmetrically to the center axis of the mold and in Separate connections for the independent supply of a Have liquid cooling medium, and with means for adjusting the of the Narrow and wide side walls formed mold cavity to different Strand dimensions and the casting cone, and with an oscillation device, and with in the wall sensors of the chambers facing the strand, with which at least the temperature differences between the individual chambers or Zones are detected and temperature sensors in the coolant supply and discharge lines are arranged, the temperature sensors as well as the temperature sensors with a Connect controller, which controls the taper of the narrow sides via an actuator and / or the comparison of the specific heat flows per chamber or zone to one another by changing the oscillation parameters.
  • the inlet and Outlet water temperature and the amount of water measured can also be regulated independently of one another.
  • the arrangement according to the invention in at least three zones and the comparison of the specific heat flows in these zones to each other allows an asymmetry especially to be recognized in the diving spout area.
  • a non-uniform Heat transfer due to turbulence of the steel in the mold is also recognizable.
  • a possible deviation in the middle of the mold is accompanied by longitudinal cracks in the Strand surface up to breakthroughs (adhesives). These longitudinal cracks occur especially in the middle of the slab area next to the central axis in the area of the Immersion spout, i.e. in the area of the relatively thinner slag lubrication film.
  • This thinner slag lubrication film leads to an increased heat flow and thus to a non-uniform partial strand shell formation with regard to the increased Thickness, the reduced temperature and the increased shrinkage.
  • This non-uniform partial strand shell formation leads to longitudinal cracks and in Extreme case for gluing the strand in the middle of the broadside of the mold and for Breakthrough.
  • the device allows the strand to move in Detect direction of one of the narrow sides with a corresponding risk of breakthrough as a result of hangers, which are then counteracted by conicity regulation can.
  • the invention therefore not only allows a change in the casting parameters during of casting, especially to ensure breakthrough, but also development the mold shape in interaction with the immersion nozzle, both inside and out outside and the mold powder to an optimal system "mold".
  • FIG. 1 shows schematically the structure of a plate mold in cross section and Fig.2 in Longitudinal section ..
  • the picture shows a straight-wall mold for the continuous casting of slabs.
  • the broad sides have a first side segment 11 and a middle segment 13 on, each having chambers or a first segment 21 and a center segment 23, which have vertically arranged bores for guiding the cooling water.
  • An adjustable device 33 is adjustable between the broad sides Narrow side 31 clamped.
  • each of the cooling chambers have, or a side segment 22 and a center segment 23, the Has cooling holes.
  • the center segments are 13 and 23, respectively further divided into zones 14 and 15 or 24 and 25.
  • Adjustment device 33 is adjustable by means of an actuator 63.
  • the broad sides 11 to 15 and 21 to 25 and the narrow sides 31 and 32 have feeds 51, 53, 55, 57 and discharges 52, 54, 56 and 58, through which a cooling medium can be fed in and out.
  • An immersion pouring tube 41 or 42 is introduced into the mold interior of the mold.
  • thermal sensors 61 and in the supply and discharge lines 51 to 58 thermal sensors 64 are arranged, which are connected to a controller 62, which acts on the actuator 63 or an oscillation device, not shown .
  • the side view of the mold is shown with the identical positions already mentioned.
  • the lower adjusting device 34 or 36 of the narrow sides 31 or 32 is also shown.
  • the die mouth is designated 29
